Why?  Because a circle is a two dimensional object on a single plane. A sphere is a round three dimensional object. A sphere and a circle aren't the same.

Great. Now just connect where the concept of a sphere was a concept when the Earth was referred to as a circle.

And explain that mathematical concept in the terms a fisherman would have used a few thousand years ago.

Aaaaand... go!
